Amoebozoa is a major, early-diverging lineage of eukaryotes, containing at least 2,400 species. At present, 32 mitochondrial genomes belonging to 18 amoebozoan species are publicly available. A dearth of information is particularly obvious for two major amoebozoan clades, Variosea and Tubulinea, with just one mitochondrial genome sequenced for each. The main focus of this review is to summarize features such as mitochondrial gene content, mitochondrial genome size variation, and presence or absence of RNA editing, showing if they are unique or shared among amoebozoan lineages. In addition, we underline the potential of mitochondrial genomes for multigene phylogenetic reconstruction in Amoebozoa, where the relationships among lineages are not fully resolved yet. With the increasing application of next-generation sequencing techniques and reliable protocols, we advocate mitochondrial

  • Comparative Proteomic Profiling of Newly Acquired, Virulent And
    www.nature.com/scientificreports OPEN Comparative proteomic profling of newly acquired, virulent and attenuated Neoparamoeba perurans proteins associated with amoebic gill disease Kerrie Ní Dhufaigh1*, Eugene Dillon2, Natasha Botwright3, Anita Talbot1, Ian O’Connor1, Eugene MacCarthy1 & Orla Slattery4 The causative agent of amoebic gill disease, Neoparamoeba perurans is reported to lose virulence during prolonged in vitro maintenance. In this study, the impact of prolonged culture on N. perurans virulence and its proteome was investigated. Two isolates, attenuated and virulent, had their virulence assessed in an experimental trial using Atlantic salmon smolts and their bacterial community composition was evaluated by 16S rRNA Illumina MiSeq sequencing. Soluble proteins were isolated from three isolates: a newly acquired, virulent and attenuated N. perurans culture. Proteins were analysed using two-dimensional electrophoresis coupled with liquid chromatography tandem mass spectrometry (LC–MS/MS). The challenge trial using naïve smolts confrmed a loss in virulence in the attenuated N. perurans culture. A greater diversity of bacterial communities was found in the microbiome of the virulent isolate in contrast to a reduction in microbial community richness in the attenuated microbiome. A collated proteome database of N. perurans, Amoebozoa and four bacterial genera resulted in 24 proteins diferentially expressed between the three cultures. The present LC–MS/ MS results indicate protein synthesis, oxidative stress and immunomodulation are upregulated in a newly acquired N. perurans culture and future studies may exploit these protein identifcations for therapeutic purposes in infected farmed fsh. Neoparamoeba perurans is an ectoparasitic protozoan responsible for the hyperplastic gill infection of marine cultured fnfsh referred to as amoebic gill disease (AGD)1.

  • Emerging Genomic and Proteomic Evidence on Relationships Among the Animal, Plant and Fungal Kingdoms
    Review Emerging Genomic and Proteomic Evidence on Relationships Among the Animal, Plant and Fungal Kingdoms John W. Stiller Department of Biology, East Carolina University, Greenville, NC 27858, USA. Sequence-based molecular phylogenies have provided new models of early eu- karyotic evolution. This includes the widely accepted hypothesis that animals are related most closely to fungi, and that the two should be grouped together as the Opisthokonta. Although most published phylogenies have supported an opisthokont relationship, a number of genes contain a tree-building signal that clusters animal and green plant sequences, to the exclusion of fungi. The alter- native tree-building signal is especially intriguing in light of emerging data from genomic and proteomic studies that indicate striking and potentially synapomor- phic similarities between plants and animals. This paper reviews these new lines of evidence, which have yet to be incorporated into models of broad scale eukaryotic evolution.

  • Molecular Identity of Strains of Heterotrophic Flagellates Isolated from Surface Waters and Deep-Sea Sediments of the South Atlantic Based on SSU Rdna
    AQUATIC MICROBIAL ECOLOGY Vol. 38: 239–247, 2005 Published March 18 Aquat Microb Ecol Molecular identity of strains of heterotrophic flagellates isolated from surface waters and deep-sea sediments of the South Atlantic based on SSU rDNA Frank Scheckenbach1, Claudia Wylezich1, Markus Weitere1, Klaus Hausmann2, Hartmut Arndt1,* 1Department of General Ecology and Limnology, Zoological Institute, University of Cologne, 50923 Cologne, Germany 2Institute of Biology/Zoology, Free University of Berlin, Research Group Protozoology, 14195 Berlin, Germany ABSTRACT: Whereas much is known about the biodiversity of prokaryotes and macroorganisms in the deep sea, knowledge on the biodiversity of protists remains very limited. Molecular studies have changed our view of marine environments and have revealed an astonishing number of previously unknown eukaryotic organisms. Morphological findings have shown that at least some widely dis- tributed nanoflagellates can also be found in the deep sea. Whether these flagellates have contact with populations from other habitats is still uncertain. We performed a molecular comparison of strains isolated from deep-sea sediments (>5000 m depth) and surface waters on the basis of their small subunit ribosomal DNA (SSU rDNA). Sequences of Rhynchomonas nasuta, Amastigomonas debruynei, Ancyromonas sigmoides, Cafeteria roenbergensis and Caecitellus parvulus were analysed, and 2 contrasting results obtained. Firstly, we found nearly identical genotypes within 1 morphospecies (C. roenbergensis), and secondly, quite different genotypes within certain morpho- species (R. nasuta, A. sigmoides and C. parvulus). In addition, high genetic distances between the dif- ferent strains of A. sigmoides and C. parvulus indicate that these morphospecies should be divided into different at least genetically distinguishable species. In contrast, some heterotrophic nanoflagel- lates must indeed be regarded as being cosmopolitan.

The mitochondrial genome of P. mycophagum was deposited under the Accession number KY75056 and that of P. aurantium under the Accession number KY75057. The RNAseq reads can be found in Bioproject Accession PRJNA338377. All sequence and annotation data are also available directly from the authors. The P. aurantium strain is deposited in the Jena Microbial Resource Collection (JMRC) under accession number SF0012540. Abstract Establishment of multicellularity represents a major transition in eukaryote evolution. A subgroup of Amoebozoa, the dictyos- teliids, has evolved a relatively simple aggregative multicellular stage resulting in a fruiting body supported by a stalk. Protosteloid amoeba, which are scattered throughout the amoebozoan tree, differ by producing only one or few single stalked spores.

  • Protist Phylogeny and the High-Level Classification of Protozoa
    Europ. J. Protistol. 39, 338–348 (2003) © Urban & Fischer Verlag http://www.urbanfischer.de/journals/ejp Protist phylogeny and the high-level classification of Protozoa Thomas Cavalier-Smith Department of Zoology, University of Oxford, South Parks Road, Oxford, OX1 3PS, UK; E-mail: [email protected] Received 1 September 2003; 29 September 2003. Accepted: 29 September 2003 Protist large-scale phylogeny is briefly reviewed and a revised higher classification of the kingdom Pro- tozoa into 11 phyla presented. Complementary gene fusions reveal a fundamental bifurcation among eu- karyotes between two major clades: the ancestrally uniciliate (often unicentriolar) unikonts and the an- cestrally biciliate bikonts, which undergo ciliary transformation by converting a younger anterior cilium into a dissimilar older posterior cilium. Unikonts comprise the ancestrally unikont protozoan phylum Amoebozoa and the opisthokonts (kingdom Animalia, phylum Choanozoa, their sisters or ancestors; and kingdom Fungi). They share a derived triple-gene fusion, absent from bikonts. Bikonts contrastingly share a derived gene fusion between dihydrofolate reductase and thymidylate synthase and include plants and all other protists, comprising the protozoan infrakingdoms Rhizaria [phyla Cercozoa and Re- taria (Radiozoa, Foraminifera)] and Excavata (phyla Loukozoa, Metamonada, Euglenozoa, Percolozoa), plus the kingdom Plantae [Viridaeplantae, Rhodophyta (sisters); Glaucophyta], the chromalveolate clade, and the protozoan phylum Apusozoa (Thecomonadea, Diphylleida). Chromalveolates comprise kingdom Chromista (Cryptista, Heterokonta, Haptophyta) and the protozoan infrakingdom Alveolata [phyla Cilio- phora and Miozoa (= Protalveolata, Dinozoa, Apicomplexa)], which diverged from a common ancestor that enslaved a red alga and evolved novel plastid protein-targeting machinery via the host rough ER and the enslaved algal plasma membrane (periplastid membrane).

Mycosphere 6(3), 356–384, doi 10.5943/mycosphere/6/3/11 Abstract A total of 299 substrate samples collected throughout the Sultanate of Oman were analyzed for myxomycetes and myxomycete-like organisms (MMLO) with a combined approach, preparing one moist chamber culture and one agar culture for each sample. We recovered 8 forms of Myxobacteria, 2 sorocarpic amoebae (Acrasids), 19 known and 6 unknown taxa of protostelioid amoebae (Protostelids), and 50 species of Myxomycetes. Moist chambers and agar cultures completed each other. No method alone can detect the whole diversity of myxomycetes as the most species-rich group of MMLO. A significant overlap between the two methods was observed only for Myxobacteria and some myxomycetes with small sporocarps.
